Matlab to trigger Analog Discovery 2

I would like to trigger the generation of waveforms by the Analog Discovery 2 using Matlab, but the function addAnalogOutputChannel is not working (even in the exemple code that you are providing). Thank you

What error message is shown?

There are no devices available.

My AD2 is plugged and is working well with WaveForms.

Thank you for your help, the coding world is new for me...
